Hi Monica, very nice indeed! Some have remarked where some passages are not as smooth. I haven't learned this piece, but like many other Chopin pieces it's difficult to play legato with fluidity and make all the parts fit seamlessly to tempo. Don't harp on the small pinkie syndrome - you're not the only one.
A piece like this really depends on the action of the piano and a légère
style of legato. Just like Chopin's fingers, if the action is supple, it will reward you. If the action is not totally responsive, playing such a piece smoothly is more awkward and requires more effort. More effort leads to tightening of the wrists, and that in turn leads to jerky movements. I remember on my parents Bradbury while growing up, the action was stiff, and it would be next to impossible to play a piece like this and have all the passages come together smoothly.
You are at the point where with a little more playing the fluidity will come in time. These kind of pieces demand continual performance to have it sound fresh and legato. Now that you've recorded the piece and there's no more pressure, I bet you a trip to Paris that you'll be the queen of legato with this piece if you keep on playing it...
Nonetheless, a beautiful recording of a delightful Impromptu!
